Application lcd April 2S, 1914.. Seria! T01/.ZZ eti/10m 'it may concernBe it known that I, HUGH W. SANFORD, citizen of the United States,residing at ot' Tennessee, have invented certain new and of `which thefollowing is a specification, reference being had therein tc theaccompanying drawing.

This invention relates to wheels of a Char acter more especiallydesigned for service in connection with mining Acar constructions7`though not limited to such use.

The invention hasniore particularly to deal with that type of car Wheelwherein the wheel hub is loose on thc axle, and has a movable bearing inthe pedestal box, and in the preferred construction, a pedestal bear'fing for the axle and wheel hub is provided at the outside of the wheel.

One of the objects of the present invention is the provision of a noveltype of wheel and hub, the hub being of a construction to adequatelytake care of the heavy end thrusts of the carin going around. thecurves, and lto reduce friction7 and to also provide an intermediatechamber between the hub and axle for the reception of oil or otherlubricant, the ends of the bearing provided by the huband vassociatedparts largely preventing the oil frein readily working out at the endsof the bearing.

Another feature of the invention resides in the pro-vision of an oilreservoir in the wheel proper, such reservoir being in communicationwith the oil chamber of the A further improvement embodied in theinvention is the provision of a novel con struction and arrangement ofself-contained roller bearings within the Wheel hub, therebyeliminating' the necessity of cage bearings or the like for retainingthe individual rollers in place.

Further, the invention includes a novel and eliicient mining car Wheel,simple in Stillv further improvements and novel details in theconstruction and arrangement of the various parts will be appreciatedfrom the descriptionl to follow, which, for a clear understanding oftheevention iS te be eeesidered in connection with 'the accompany- 'ingdrawings, forming a part hereof, and

wherein is disclosed, furthe purpose oit illustratioma convenient andsatisiaetory embodiment of the invention.

in the drawings: nFigure l is a vertical section of the wheel and hubapplied to the car frame; Figs. Q, and 3 are cross sectional views onlines 2 2 and f-B of Fig. l.

With more particular reference to the drawings, 'wherein like referencenumerals refer to corresponding parts throughout the several views, 1 isa wheel having a central annular chamber 2, forming a reservoir for oil.`or other suitable lubricant, the outside of the wheel. having asuitable opening for the insertion of the oil. Threaded to said openingis a suitable nut 4 having an opening therethrough, and positioned atthe inner end oi the nut is an apertured disli 6. f

7 is a valve adapted to seat against a shoulder ofthe nut et, whereby toclose the passage 5, the said valve being normally held toits seat asbyasuitable spring 8, interposed between the valve 7 and the apertured disklG. The wheel has a suitable hub 9, -conveniently integral therewith,and projecting laterally from opposite sides ofthewheel.

10 is a section of the car trarne arranged at the outside of the Wheeland having connected thereto, in any desired manner, a pedestal. section11, adapted to loosely receive the end of the axle 12, the pedestalsection having an enlarged inner end 13 adapted to be sleeved upon theouter hub portion of the Wheel. Preferably a suitable metallic Washer14; is interposed between the outer end of the hub 9 and the shoulderportion 13 of the. pedestal part 18.

The pedestal part 11 is preterab'ly removably held in place, 4as bybolts, 1.5, engaging the lframework of the car, A suitable packing, asof felt, 1G, may be interposed between the outer end ofthe hub and theenlarged portion of the pedestal member surrounding the same. 17 is whatmay be called a dustboX, the same beingsleeved upon the axle and securedthereto as by a pin 18, saidbox having an enlarged recessed portion 19sleeved upon the inner end of the hub 9. 'A yieldable packing, as offelt, 20, may be interposed between` the enlarged portion 19 of the dustbox and the periphery of the in- Aner end of the hub. The body portionot the hub is preferably spaced aboutthe periph.-

eryoffthe axle, whereby tolprovide a cham'-y ber for the reception ofsuitable. rollerbearings 21, a suitable metallic lining'22 beinginterposed between the hub 9 and said roller suitable metallic thrustwasher 25 engaging a shouldered portion 26, of the dust box 17.

The flange 23 has at its inner zsurfacean-in- I bearings.

A The inner endof .the-hub 9 .has an inwardly projecting annular nange23,' formfinge' substantial closure for the inner end 'olined shouldery'27 A 'cup shaped washer 28 is'position'ed within the outer end of theshaped washerr28, at the outer end thereo't,v form end walls for the oilreservoir provided hub and secured thereto as bybolts, 29, said Washerforming la; substantial closure `for the outerendofthe hub and having'an inwardly.

projecting annular flange 30. The flange 23, atthe inner end of the hub,'and the cup by the hollow ,hub 9, and also end bearings for the rollerbearings' 21, which latter have reduced terminals or journals 21aasishown..

The hub 9 has an annular chamber 31 communicating with transverseopenings 32 con necting with the oil reservoir of the wheel 1. Thechamber 31 also communicates with openings 33, projecting through themetallic.

lining 22. In this way the oil inds a passage from the oil reservoir otthe -wheel into the `roller bearing chamber and aboutA the axle', asmall portion thereotl finding an exit at the ends of the hub chamberi'jor lubricating that portion of the axle adjacent the ends of the hub.l

If desired, a more or less heavy lubricant may be inserted in thereservoir of the wheel chamber by removing the nut 4f.. Where a thinlubricant is used, the same' may 4be in serted through the valve closedopening 5, the same finding an outlet through the apert-ured disk 6 atthe inner end of the nut.

. mining car wheel constructed as above@ ,I is exceedingly.strong,while,at the same time" simple in construction and very easily takenr Thewheels are `readily oiled i care of.v through the openings 5, as abovedescribed, the oil flowing down through the ports of the hub and liningto the roller bearing chamber, and the valve controlled opening` 5 isreadily accessible from underneath the pedestal box 13. The provision ofthe flange 23' at the inner end of the hub and the cupsha ed washer 28at the outer end thereof ma es the rollerbearing a self-contained one,so that the wheel may be readily taken 0E the axle and handled as asolid hub wheel, the bearings being kheld in place. The wheel is held inplace by the pedestal 13, which latter forms a closed end bearing forthe axle,

and a closed end fortheouterend oftloc` of the pedestal. Likewise thewheel may be removed :Erom' the "axle, asrdesired, by the which may beaccomplished vby the removal diameter of the friction surface againstthe boxing 17 so that'there wilt be less wear andincidentally'lessfriction at this point.

ers is done away `witlfifby'reasonfofthe peculiar constructionofbeari'ngs, it being found in practice that the pressurevon the rollersis on the bottom'roller, the roller bearings falling by gravity tothepoint of pressure, and because of the peculiar construction of rollersmaybe quickly. .and cheaply replaced as independent units'.

A suitable housing 35 is preferably provided, the same overlying theupper section of the wheel and having side flanges 36', resting upon andremovably secured as by bolts 37 to the car frame. f What I claim is "ofa rotatable. axle having an yabutment ing ,an inner hub portion tocontact with said abutment, and the outer end of the axle projectingthrough the hub, and means be detachably secured to the trame of thecar, said pedestal member being sleeved upon theend of the axle andhaving an end of thehub of the wheel. 2.
